Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery. Background Art

[0002] In the design of modern electronic products, batteries are the core components of energy supply, and their reliability is crucial. Especially in the fields of outdoor equipment, wearable devices, and medical equipment, the waterproof performance of batteries directly affects the safety and service life of the equipment. Therefore, higher requirements are placed on the waterproof design of batteries.

[0003] Existing battery waterproof designs mostly rely on adding waterproof rings or sealing gaskets between the battery housing and the output port to prevent moisture from entering the battery. Although this method can prevent moisture intrusion to a certain extent, in order to ensure effective sealing, the waterproof ring needs to occupy a certain amount of space, which undoubtedly increases the design difficulty for modern electronic products that pursue thin and short designs. At the same time, due to the diversity of different product designs, universal waterproof rings often cannot meet the sealing requirements of all designs, which leads to the need to customize waterproof rings of different specifications for different products in actual applications, increasing production costs.
